Source for cheap 17Hz subwoofer? (Evil Science Experiment)?
Do any of you fellow scientists know of a good source for inexpensive subwoofers? I need it to go at least as low as 17Hz, but due to the nature of the experiment, I don't want to use expensive equipment (in case I accidentally wind up epoxying the speaker to something else (it happened with the egg experiment)).
I have no grant money -I just need to find a good subwoofer source (or plans... I've got plenty of wire sitting around).

It's very difficult to get much response at 20 Hz, let alone 17 Hz. You can buy multi-thousand dollar woofers that don't go much below 25 Hz.
If you just need that one frequency, you can tune the whole thing. Basically build an organ pipe, and get lots of response at that frequency.

Just about any speaker will respond to 17 Hz.
The #1 question is how much subsonic power do you need?
The #2 question how much distortion can you tolerate? How efficient?
And so on…
